Rumors of a folding iPhone span over a decade, with Apple's first foldable expected to launch soon. While the marketing name remains uncertain — iPhone Fold or iPhone Ultra — multiple sources confirm development is underway. Analysts, leakers, and Apple's own code point to a foldable iPhone in the works, though Apple has outright refused to comment publicly. Samsung's Galaxy Fold and Galaxy Z Flip have already established the foldable market, putting pressure on Apple to deliver.

In March 2026, a reliable leaker suggested Apple was developing several "Ultra" tier products, including a foldable iPhone, potentially branded as iPhone Ultra. A Weibo leaker corroborated this, and an August 2026 report claimed the name "iPhone Ultra" was used internally. However, earlier "Ultra" branding rumors from the same source proved inaccurate, casting doubt. AppleInsider has used both iPhone Fold and iPhone Ultra interchangeably.

Supply chain research has reportedly continued for years, with alleged technical specifications, board designs, and dummy units surfacing. Despite the speculation, Apple's typical secrecy means the final name and launch timeline remain unconfirmed.
